But the fame he longed for and, with an almost childlike naïveté, claimed as his due, was short-lived. It barely touched him and passed him by. Yet he deserves remembrance, if only for his versatility. While it is chiefly as a poet that mention is made of him in encyclopedias and other books of reference, he was capable, but for his temperamental disabilities, of shining in many lines and in one pursuit other than poetry he has left a lasting memorial. He studied law, was admitted to the bar and never practiced. He served his medical apprenticeship under his good friend Dr. Eli Ives of New Haven, took his degree, practiced a little and, though he was always afterward known as "Doctor," abandoned the profession--except that later in life he was post surgeon at Boston till his abhorrence of examining recruits compelled him to relinquish the work. At one time he thought of entering the ministry and he was always an authority on theology and dogma. He gave up his appointment as a professor of chemistry at the Military Academy at West Point because in going to his quarters he had to use the same hallway with other officers. He was a learned botanist and a linguist of rare attainments. In 1827 he carried through successfully the immense task of correcting the proofs and supervising the publication of Webster's unabridged dictionary--and seems to have been happier in this work of enormous detail than at any other time of his life. But it was as a geologist that his most valuable practical work was done. His "Report on the Geology of Connecticut," published in 1842, was the result of five years of arduous labor and is a sufficient monument for any man. "While engaged in this survey," he wrote, "I can confidently say that I have been laborious and diligent. While traveling, it was my practice to rise early, in the longer days generally at dawn; in the shorter generally I got my breakfast and was on my way by daybreak, I continued, scarcely with any relaxation, as long as I had daylight and then was generally obliged to sit up till midnight, not unfrequently till one o'clock A. M. in order to complete my notes and arrange my specimens. This was continued, not only week after week, but month after month, almost without cessation." Under the law Percival could not be paid till his report had been approved by the governor. It is characteristic of the whimsical geologist that he refused to submit to this approval by one whom he considered incompetent to pass upon his labors and it was only by the ruse of a friend who got possession of the report and presented it to the governor, who at once approved it, that Percival secured his pay.
